RIPLEY COUNTY, Ind. (WKRC) -- Neighbors in several local communities were afraid an earthquake struck when they felt their homes shake. We received emails and posts on the Local 12 News Facebook page Wednesday afternoon about homes shaking in parts of Dearborn and Ripley Counties. Turns out the Indiana Air National Guard says it was detonating old explosives at the jJefferson Proving Ground near Madison. There will be more shaking one week from Wednesday, officials say more detonations are scheduled then.
